Graph the equation by plotting points.

\r\n" );
document.write( "y = -5\r\n" );
document.write( "\r\n" );
document.write( "Since the variable x does not appear in the equation,\r\n" );
document.write( "x can be any number we choose.  However the value of\r\n" );
document.write( "y can only be -5.\r\n" );
document.write( "\r\n" );
document.write( "So to make a table of values of points, we don't need\r\n" );
document.write( "to do any calculations, but just pick some arbitrary\r\n" );
document.write( "values for the x-coordinate, the variable that does not \r\n" );
document.write( "appear in the equation, and use -5 for the y-coordinate:\r\n" );
document.write( "\r\n" );
document.write( "  x  |  y  |  (x,y)\r\n" );
document.write( " -7  | -5  | (-7,-5)\r\n" );
document.write( " -4  | -5  | (-4,-5)\r\n" );
document.write( "  1  | -5  |  (1,-5)\r\n" );
document.write( "  5  | -5  |  (5,-5)\r\n" );
document.write( "  8  | -5  |  (8,-5)\r\n" );
document.write( "\r\n" );
document.write( "So we plot those 5 points:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now we just draw a line through all those points (I'll draw it\r\n" );
